Ofcom approves Hereford and Worcester DAB frequency change

Ofcom has agreed to allow local DAB multiplex operator MuxCo to launch its new multiplex for Hereford and Worcester on the frequency previously assigned to regional digital radio in the West Midlands.

Following a reorganisation of the DAB digital radio service in the West Midlands last month, the regional DAB multiplex on VHF Block 12A closed down. MuxCo applied to Ofcom to change the frequency assigned to its Hereford and Worcester multiplex from VHF Block 10B to the now vacant frequency at Block 12A.

Under the rules, Ofcom had to undertake a consultation exercise, but did not receive any responses.

Ofcom replied "As MuxCo's proposal to change the frequency of the local radio multiplex service would have no impact on the range of local digital sound programme services (proposed to be) available in the Herefordshire & Worcestershire area, Ofcom was satisfied that this statutory criterion had been met."

"The proposed frequency change requested by MuxCo is part of a revised frequency plan which is designed to enhance the coverage of local DAB services across the UK as a whole. As such, the proposed alternative frequency (12A) is available, and the knock-on implications for other multiplexes is positive, in that changing the frequency of the Herefordshire & Worcestershire local radio multiplex service will reduce the levels of interference between local DAB multiplexes on the same frequencies and thus improve local DAB coverage overall. Ofcom was therefore satisfied that it should approve this request."

According to MuxCo, it will shortly commence test transmissions at two transmitter sites -  Ridge Hill and Malvern. Transmissions from Bromsgrove will follow later.

Hereford and Worcester DAB services are expected to reach 231,465 out of 339,323 households within the two counties. Stations making the move to digital include BBC Hereford and Worcester and Free Radio (Worcester).
